JOSEPH M. OLSON, OF CHICAGO, ILLINOIS.

HOLLOW noon.

To all whom it may concern:

Be it known that l, JosnrI-i M. OLSON, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hollow Doors, of which the following is a specification.

My present invention relates to improvements in doors for dwellings, and the especial object of my improvements is to provide a combination door having in a unitary structure the advantages of a screen door and a storm door, the latter adapted to ad Init light.

Further objects are to provide a door of the type referred to, of simple and economical construction, in which the transformation from the screen door type to the storm door type may be quickly and easily effected, and that will effectively exclude the elements when used in its storm door capacity.

A further object is to provide a combina tion screen and storm door that will be neat in appearance and conform, so far as possible, to the designs of ordinary doors in common use.

Having the foregoing especial objects, and others of general utility in view, I have designed the combination door which I have illustrated in a preferred form in the accompanying drawing forming a part of this application, in which Figure 1 is a view in inside elevation of a door constructed according to my invention in which both the screen and storm features are shown, and in which a portion of the door is broken away to disclose certain details of construction; Fig. 2 is an enlarged fragmental sectional view on the line 22 of Fig. 1; Fig. 3 is an enlarged sectional view on the line 38 of Fig. 1; Fig. 4: is an enlarged sectional view on the line 4 l of Fig. 1; and Fig. 5 is an enlarged fragmental detail showing the manner of mounting the adjustable sash supporting molding which forms a feature of my invention.

Referring to the details of the drawing, the reference character 6 represents the opposed side walls or stiles and connecting members of a door between which members is a space 6 which is substantially co-extensive with the door except at the outer margins where filler pieces, such as 6, are inserted. In the upper and inner cross mem- Specificatipn of Letters Patent.

her or rail of the door is a slot 6* which extends transversely of the door and has its upper and lower walls curved, as shown in Fig. 2, said slot communicating with the space (3 throughout the entire width of the latter.

T represents a rectangular window sash of ordinary construction except that the hand receiving openings facilitate theraising of the sash as 7 are placed in the upper cross bar of sash instead of in the lower for reasons that will be apparent. This sash is equipped with a pane of glass represented by the reference character 8. Along the upper margin of the top cross bar of the sash frame 7 are a series of hooks 9 which are adapted to engage suitable holes provided therefor in a metal strip 10 which is secured to the lower edge of a sheet of screen wire 11, the upper edge of which is secured to a spring roller such as is common in connection with ordinary window shades, the pintles 11" of said roller being mounted in brackets 12 which are secured to the inner face of the door 6 adjacent the ends of the slot 6. The screen wire fabric 11 is of the soft or ductile type to facilitate its being wound upon and unwound from the spring roller. The fabric passes from the roller through the slot 6 down through the space 6 and the side margins of the screen are covered by the molding and adjacent portions of the door, as clearly shown in Fig. l. The side stiles of the window 8 also slide in the same grooves or slideways provided by the spaced side members of the door.

The spring in the roller carrying the spring fabric 11 will be of sufiicient tension to nearly if not quite counterbalance the weight of the sash 8, but, in order to effectively support said sash when in its closed position, and also to exclude the elements from entering the slideway in the lower portion of the door when the sash is raised, I provide a combined molding and stop represented by the reference character 13. This spring has a series of transverse slots 13 cut therethrough and extending through said slots and into the upper edge of the inner wall of the center cross rail of the door are screws 14. The strips 13 are sufficiently wide to extend across the opening 6 when said strips are pushed inwardly, as indicated by dotted lines'in Fig. 4:, and when in this position it is obvious that said strip will support the sash the lower rail of which will rest upon the strip. The screws will prevent the strip from being displaced when drawn away from across the opening 6.

WVhen it is not desired to use the screen supported by said door, a screen fabricmounted on said roller and adapted to slide within the hollow door, means for detachably securing the lower edge of said screen to said sash, and means for supporting the sash in its closed position, said means comprising an elongated strip adapted to be bodily moved transverse to its length under the lower edge of said sash.

2. A hollow door having a slot in its upper and inner face, a sash slidably mounted in said door, a roller mounted on said door adjacent said slot, a screen attached to said roller and adapted to slide through said slot and within said door, means for detachably securing the lower edge of said screen to the upper edge of said sash, and means for supporting said sash in its closed position, said means comprising an adjustable stop mounted at the lower edge of the sash opening in said door and adapted to pass bodily under the lower edge of said sash.

In testimony whereof I aflix my signature in the presence of two witnesses. JOSEPH M. OLSON.
